Accessible critiques of objectivism

Much to my horror, someone I care deeply about is becoming interested in objectivism. I need a VERY accessible article, podcast, etc. that explains the problems of objectivism. Huemer's critique of objectivism is close to something like what I'm looking for. I hesitate to pass it along because of how much it depends on the premise-conclusion form of Rand's argument; I worry they will have a hard time keeping up with this.
